To all whom it may concern:

Be it known that we, Amman L. Bn'rrs and PAUL S. SHIELD, citizens of theUnited States, and residents of Cincinnati, in the county of Hamiltonand State of Ohio, have invented a new and useful Bumper forTank-Vehicles, of which the following is a specification.

The invention has reference to tank vehicles, such as oil tank wagonsand trucks, in which the contents of the tank (usually compartmente'daredispensed from faucets at the rear. o guard against injury to thesefaucets and the loss and danger resulting from escape. of oil orgasolene in event of their brea able to protect them with a bumper; butthis makes it-diificult to place the buckets on'and off the hooks on thefaucets, and there has consequently been dissatisfaction with the use ofsuch bumpers, causing them in some quarters to be rejected. To meet thissituation special bucket-guiding hooks have been provided, as disclosedin l atents No. 1,330,623 of February 10, 1920,and No. 1,332,614 ofMarch 2, 1920. The present invention aims to overcome the diificulty ina still simpler and more satisfactory manner, while preserving the fulladvantage of the bumper; and this is accomplished by constructing thebumper sothat it is normally-rigid and can be readily lifted up to clearthe faucets for application and removal of the buckets.

he preferred embodiment of the construction will now be brieflydescribed reference being had to the 'accompanyin rawin s, wherein:

igure 1 is a plan view of the rear portion of an oil tank vehicle,illustrating the invention;

Fi 2 is a side elevation, showing in dotted llnes the bumper-bar raisedand swung back out of the way;

The drawing illustrates the tank 1- of an oil tank truck, 2 are sidesills representing a supporting frame, 3 the bucket-box at-the rear endof the tank, and 4 the faucets, be-

low the bucket-box, on the. ends of pipes leading from the compartmentsof the tanks.

The faucets are of usual construction, and

have hooks 5 at the back on which tohang lpeciflcation of LettersPatent.

the handles of buckets, in which the oil and gasolene are carried to thecustomers storage tanks. It is ordinarily an awkward matter to get thehandles on and off these hooks, when the faucets and bucket-box areprotected by a rear bumper.

The bumper of this invention is designated generally 6. It may be saidto be composed of a fixed part, comprisin side members 7, and a movablepart, consisting of a bum er-bar 8.

The .si e members 7 are bolted to the .rear ends of side sills 2 of themounting or of the chassis, and are offset laterally outward at theirintermediate inclined portions 10, and have straight parallel rearportions 11.

vThe side mem ers and the bar 8 are advantageously made of channels, andthe ends 12 of the bar preferably extend beyond the portions 11 and arecurved forwardly; but it will be understood that these and other detailsmay be varied.

Two plates or members 13 are fixed to the bumper-bar, so as to projectforwardly at points somewhat inward of the end portions 12, as bybending the forward parts 14 of the plates outward and riveting them tothe back of the channel. These plates normally extend alongside the rearportions 11 of the side members, and in their forward portions arelongitudinal, closed-end'slots 15. Said slots receive pivot studs 16which project outward from the portions 11 of the side members, slottedpivotal connections being thus afforded between the bumper-bar and theside members, permittin the bar to belifted up so as to ex ose t efaucets and their hooks 5; the pivots being properly and overlapping thebum ii-bar at the bottom, and another pair 0 plates 18 riveted to theside members at the top and overlappin the top of the bar. The rear endsof the atter jaw members are desirably curved and rolled as shown at 19,for strength and 0 facilitate lifting and replacement of the Thebumper-bar can thus be pulled out from the confinement of the lock,preparatory to being swung upward out of the way. It is normallrestrained, however, by springs 20, which hold the bar to its seat aainst the ends of the side members an within the jaws of the lock. Saidsprlngs may be hooked at one end to eye-bolts 21 on the bumper-bar, andat the other end to the pivots 16 between the heads thereof and nuts 22.The fact of the bumper bar being in abuttin relation to the side memberssaves the pivots from shock in event of collision.

What is claimed as new 1s: 1. In a tank vehicle, the combination withthe frame and rear faucets, of a bumper on the rear end oftheframeprotecting the fau cets, said bumper comprising side membersextending rearward from the frame, a liftup bumper-bar movably connectedto theside members, and means for locking the bar to said side members.

2; In a tank vehicle having faucets at the rear end, a bumper protectmgsaid faucets comprising side members extending rearward from the vehicleand-having their rear portions ofi'set laterally outward,

a bumper-bar having members projecting forwardand pivoted to said offsetrear portions of the side members, and means for looking the bumper-barto the side members. r

r 3. In a bumper of the kind described, the combination of side members,and a bumperbar pivotally connected to the side members soas to swingup, the bumper-bar being in abutting relation to the side members in itslowered (Position so'that the pivotal joints are save from the shock ofcollision.

4. In a bum er of the kind described, the combination 0 side members, abumper-bar having loose pivotal connections with said side members sothat the bar can be swung up, the bumper-bar in its lowered positionabutting against the side members, and spring means holding the bartight to the side members.

5. In a bumper of'the kind described, the combination of side members,and a bumperbar having members overlapping the side members and looselypivoted thereto so that the bar can be swung up, the bar being inabutting relation to the ends of the side I members in the loweredposition.

6. In a bumper of the kind described, the combination of side members, abumper-bar 1,see,sss

having loose pivotal connections with said side members so that the barcan be swung up, the bumper-bar in its lowered osition being in abuttingrelation to the si( e members, and a lock for the bumper-bar.

7. In a tank vehicle having faucets at the rearend, a bumper protectingsaid faucets, comprising side members, and a bumper- .bar having slottedpivotal connections with the-side members enabling it to be pulled outand swun up to clear the faucets, together with-a 100 between thebumper-bar and side members disengaged by pulling out the bumper-bar,and springs for maintaining the-parts in locked relation.

8. A bumperiof the kind described comprising side members, andamovablepart comprising a bum er-bar having slotted pivotal connections with theside members enabling it to be pulled out and swung up, together withupper and lower jaws on one of the parts normally confining the baragainst vertical movement while permitting disengagement, and springsopposing such disen and a movable part comprlsing a bumperbar havingslotted lates extending therefrom alongside the side members in engagment with the pivots, together with upper and lower jaws on one of theparts receiving the other part, and springs connected to the bar and tosaid pivots.-

11. A bumper of the kind described, comprisin side members, a bumper barhaving slotte pivotal connections with the side members enabling itto bepulled out and swung up, jaw members fixed to the side members andoverlap ing the top and bottom of the bumperar, and springs arranged todraw the bumper-bar against the side members between said jaw members.
